Tendency to shun very attractive members of opp. sex - is that weird of me?

I’ve noticed in my years of dating and being on Match.com etc. that I tend to shun very attractive candidates, as if I’m pre-emptively discounting their qualities or playing devil’s advocate e.g. if they’re still available despite being so good looking, there must be something wrong with them. The bimbo effect doesn’t really apply here coz I don’t think of their looks as a reflection of their intelligence – it’s just that I immediately assume other faults or character deficiencies. Am I crazy or do others also think the same way?

BTW it’s not like I go for the extreme opposite & choose to date unattractive candidates; it’s just that the VERY attractive immediately seem suspect to me. I know I’m being irrationally biased but it’s hard to shake…
